A nurse teaches a client who is prescribed a central vascular access device. Which statement should the nurse include in this clients teaching?
- A. You will need to wear a sling on your arm while the device is in place
- B. There is no risk of infection because sterile technique will be used during insertion.
- C. . Ask all providers to vigorously clean the connections prior to accessing the device.
- D. You will not be able to take a bath with this vascular access device.
Correct Answer: C
Rationale: Correct Answer: C
Rationale:
1. Choice C is correct because it emphasizes the importance of cleaning connections before accessing the device to prevent infection.
2. Sterile technique during insertion cannot guarantee no risk of infection (Choice B).
3. Wearing a sling is unnecessary for a central vascular access device (Choice A).
4. The statement about not being able to take a bath is not accurate and is not a common restriction (Choice D).

A client at risk for developing hyperkalemia states, 'I love fruit and usually eat it every day, but now I can't because of my high potassium level.' How should the nurse respond?
- A. Potatoes and avocados can be substituted for fruit.
- B. If you cook the fruit, the amount of potassium will be lower.
- C. Berries, cherries, apples, and peaches are low in potassium.
- D. You are correct. Fruit is very high in potassium.
Correct Answer: C
Rationale: Rationale: Option C is correct because berries, cherries, apples, and peaches are indeed low in potassium compared to other fruits. This response acknowledges the client's love for fruits while providing suitable alternatives to manage potassium levels. By choosing these low-potassium fruits, the client can continue enjoying fruits without exacerbating hyperkalemia.
Incorrect options:
A: Potatoes and avocados are high in potassium, so they are not suitable substitutes.
B: Cooking fruit does not significantly reduce its potassium content.
D: This option lacks guidance and does not offer a solution to the client's concern about high potassium levels.
A nurse assesses a client who has a radial artery catheter. Which assessment should the nurse complete first?
- A. . Amount of pressure in fluid container
- B. Date of catheter tubing change
- C. Percent of heparin in infusion container
- D. . Presence of an ulnar pulse
Correct Answer: D
Rationale: The correct answer is D: Presence of an ulnar pulse. This is the most important assessment to complete first because the presence of an ulnar pulse indicates adequate circulation in the hand, ensuring that the radial artery catheter is not compromising blood flow. If the ulnar pulse is absent, it may signify impaired circulation and potential complications such as ischemia.
Choice A is incorrect because the amount of pressure in the fluid container is not directly related to the assessment of the radial artery catheter.
Choice B is incorrect because the date of catheter tubing change is important for infection control but not the immediate priority in this situation.
Choice C is incorrect as the percent of heparin in the infusion container is important for anticoagulation therapy but does not take precedence over assessing circulation in the hand.
. A nurse assesses a client who had an intraosseous catheter placed in the left leg. Which assessment finding is of greatest concern?
- A. The catheter has been in place for 20 hours.
- B. . The client has poor vascular access in the upper extremities.
- C. The catheter is placed in the proximal tibia.
- D. The clients left lower extremity is cool to the touch.
Correct Answer: D
Rationale: The correct answer is D. A cool lower extremity can indicate impaired circulation due to the intraosseous catheter placement, leading to compartment syndrome or tissue necrosis. This finding requires immediate intervention to prevent serious complications. Choices A, B, and C are incorrect because the duration of catheter placement, poor vascular access, and the specific location of the catheter do not directly impact circulation and tissue perfusion as significantly as a cool lower extremity.
A newly graduated nurse is admitting a patient with a long history of emphysema. The new nurses preceptor is
going over the patients past lab reports with the new nurse. The nurse takes note that the patients PaCO2 has been
between 56 and 64 mm Hg for several months. The preceptor asks the new nurse why they will be cautious
administering oxygen. What is the new nurses best response?
- A. The patients calcium will rise dramatically due to pituitary stimulation.
- B. Oxygen will increase the patients intracranial pressure and create confusion.
- C. Oxygen may cause the patient to hyperventilate and become acidotic.
- D. Using oxygen may result in the patient developing carbon dioxide narcosis and hypoxemia.
Correct Answer: D
Rationale: The correct answer is D: Using oxygen may result in the patient developing carbon dioxide narcosis and hypoxemia. In patients with chronic emphysema, their respiratory drive is often triggered by low oxygen levels rather than high carbon dioxide levels. Administering supplemental oxygen can suppress their respiratory drive, leading to carbon dioxide retention (carbon dioxide narcosis) and worsening hypoxemia. This phenomenon is known as "hypoxic drive."
Choice A is incorrect because administering oxygen does not lead to a dramatic rise in calcium levels due to pituitary stimulation. Choice B is incorrect because administering oxygen does not typically increase intracranial pressure or cause confusion. Choice C is incorrect because administering oxygen does not directly cause hyperventilation and acidosis in this scenario.
While assessing a clients peripheral IV site, the nurse observes a streak of red along the vein path and palpates a 4-cm venous cord. How should the nurse document this finding?
- A. Grade 3 phlebitis at IV site
- B. infection at IV site
- C. Thrombosed area at IV site
- D. infiltration at IV site
Correct Answer: A
Rationale: The correct answer is A: Grade 3 phlebitis at IV site. This finding indicates inflammation of the vein due to irritants from the IV catheter, supported by red streak and palpable cord. Grade 3 phlebitis involves pain, redness, swelling, and palpable venous cord. Infection (B) typically presents with signs like pus, warmth, and fever. Thrombosis (C) involves a blood clot, not a palpable cord. Infiltration (D) is leakage of IV fluid into surrounding tissues, not related to palpable cord and red streak.
